This is a very simple and easy thing to implement as they probably have the data in a NSDictionary sorted by name.  They can easily create multiple NSDirectory objects that are shorted differently, place a new UIButtons at the top of their tableview controller and give the user this sorting ability.  Very simple to implement.  Hope they do that soon!

Similar to this request from a implementation perspective.  It's all about using NSDictionary objects correctly.  Maybe these two items needs to be combined into a single feature request since they are sort of related.

I would also like to sort the recently online device list, particularly by last active date/time.
